In cold weather, your nipples will be harder and this is one of the most common causes of nipple erection. Because, nipples have their control mechanism in the form of a neurotransmitter that can cause an erection when the weather changes – at the same ones that cause goosebumps.

Hot weather, though, doesn’t cause the same reaction with our nipples.

03. Breast-Feeding

Breast feeding can cause a condition called mastitis, which is common. They include symptoms like cracking and nipple chafing. Which is one of the most common causes of breast tissue to become infected and inflamed.  

Usually, mastitis happens to breast-feeding mothers in the early days of childbirth, because of milk ducts or even bacteria that move into the breast through a chapped nipple. Applying good products like lanolin cream between feedings can help your skin to retain moisture and it will keep your nipples clean and dry.

Ovulation happens when the ovary releases an egg into the fallopian tube for fertilization. It is a part of the menstrual cycle and typically happens about 14 to 15 days before the start of the period.

Research shows that your nipples get hard and erect during this time, because of hormonal imbalances of a surge in estrogen level in the body.
